石油集输管道缩径式球阀内部流场研究
Study on Internal Flow Field of Reduced-Diameter Ball Valve in Oil Gathering and Transportation Pipeline
摘要: 在石油管道运输系统中，阀门内部流场的稳定与否，将会影响整个管道运输系统的稳定性。针对缩径式球阀内部流场研究，探讨阀门开度和通道直径对其内部流场的影响。研究方法运用了NX12.0建立几何模型，采用了Fluent软件进行数值模拟，并对缩径式球阀内部的速度分布、压力分布以及流通能力进行分析。研究结果表明，随着开度增大，最大压力和最大流速增大、最小压力减小，并加剧了湍流现象。随着通道直径增大，阀门内部的高压区和中压区压力减小，低压区压力增大，最大流速减小，并减缓了湍流现象。最后，通过对流量系数和流阻系数的计算分析，验证了不同开度和通道直径对缩径式球阀流通能力的影响。结果显示，阀门的流通能力随着开度增大而减弱，随着通道直径增加而增强。以上研究结果对缩径式球阀的设计和优化提供了重要参考，为提高石油管道运输系统的稳定性和效率提供理论支持。
Abstract: In the oil pipeline transportation system, the stability of the flow field inside the valve will affect the stability of the whole pipeline transportation system. In order to study the internal flow field of reduced-diameter ball valve, the influence of valve opening and channel diameter on the internal flow field is discussed. Research methods NX12.0 was used to establish a geometric model, fluent software was used for numerical simulation, and the speed distribution, pressure distribution and flow capacity inside the reduced-diameter ball valve were analyzed. The results show that with the increase of the opening, the maximum pressure and the maximum flow rate increase and the minimum pressure decreases, and the turbulence phenomenon is intensified. With the increase of the diameter of the channel, the pressure in the high and medium pressure areas of the valve decreases, the pressure in the low pressure area increases, the maximum flow velocity decreases, and the turbulent flow phenomenon is slowed down. Finally, through the calculation and analysis of the flow coefficient and flow resistance coefficient, the influence of different opening and channel diameter on the flow capacity of the reduced-diameter ball valve is verified. The results show that the flow capacity of the valve decreases with the increase of opening and increases with the increase of channel diameter. The above research results provide an important reference for the design and optimization of the reduced-diameter ball valve, and provide theoretical support for improving the stability and efficiency of the oil pipeline transportation system.
